Log inside Sidekiq worker

It works in rails 6:

# config/initializers/sidekiq.rb

Rails.logger = Sidekiq.logger
ActiveRecord::Base.logger = Sidekiq.logger

There is a Sidekiq.logger and simply logger reference that you can use within your workers. The default should be to STDOUT and you should just direct your output in production to the log file path of your choice.

@migu, have you tried the below command in the config/initializer.rb ?

Rails.logger = Sidekiq::Logging.logger
